| description | The invention relates to an evaluation method for general data quality based on an entropy weight method. The evaluation method comprises the following steps: (1) establishing an index data quality evaluation model according to an evaluation index; (2) optimizing an evaluation index weight according to an evaluation index model and a data quality evaluation scene; and (3) checking the data quality by using the evaluation model. According to the evaluation method, the problems of high maintenance management workload and difficulty in reusing the checking algorithm of the data quality check rule are solved. Compared with the traditional data quality check working mode, the method provided by the invention has the advantages that the writing workload of the artificial script is effectively reduced, the reuse degree of the working achievement is increased and the average working efficiency is improved by 46% or above.
本发明涉及种基于熵权法的通用数据质量评估方法，包括以下步骤：（1）根据评估指标，建立指标数据质量评估模型；（2）根据评估指标模型，结合数据质量评估场景，优化评估指标权重；（3）应用评估模型核查 |
